摘　　要：本研究在大气环境下将PbO-ZnO-SiO_(2)系非晶玻璃粉末和PbTiO_(3)晶体粉末等比例混合均匀制得了复合玻璃钎料,实现了高体积分数SiCp/6063Al复合材料和DM305玻璃之间的连接。结果表明:当封接温度为480℃,保温30 min,复合玻璃钎料完成了预氧化后的复合材料与DM305玻璃之间的连接,接头无裂纹、气孔等缺陷,剪切强度为7.55 MPa,气密性为1×10^(-8)Pa·cm^(3)/s,符合使用要求。在封接过程中,复合玻璃钎料与母材的氧化膜相溶,在复合材料一侧出现了Al元素的扩散现象。The composite glass brazing material prepared by mixing PbO-ZnO-SiO_(2) amorphous glass powder and PbTiO_(3) crystal powder uniformly in an atmospheric environment realizes the connection between high volume fraction SiCp/6063Al composite material and DM305 glass.The results show that when the sealing temperature is 480℃and the holding time is 30 minutes,the composite glass brazing filler metal completes the connection between the pre-oxidized composite material and DM305 glass,the joint has no defects such as cracks and pores,and the shear strength is 7.55 MPa.The air tightness of 1×10^(-8)Pa·cm^(3)/s meets the requirements of use.During the sealing process,the composite glass brazing filler metal is compatible with the oxide film of the base material,and Al element diffusion occurs on the side of the composite material.
